Product Description

SM G652D G657A1 MM 50/125 62.5/125 Bare Optical Fiber used For FO Cables


A bare fiber, a core with its cladding surrounded by a coating-is still very sensitive to the adverse environment regardless of


how perfect the coating is . Thus , in practice, you will find a fiber only in some protective enclosure, which is called fiber-optic cable,


Since optical fiber is the main transmission medium in modern telecommunications .


Bare glass fibers are based on silica or other glass materials. The glass surface is susceptible to abrasion and mechanical flaws. To protect the cable from the environment, the buffer coating or jacket fits over the core and cladding.


The diameter ranges from 250μm to 900μm, usually 250um for single mode and multimode fibers, but 400um is also very common in polarization maintaining fibers. It provides mechanical protection while allowing for flexibility in the fiber.


 It provides mechanical protection while allowing for flexibility in the fiber.

The buffer coating is usually made of a soft or hard plastic such as acrylic or nylon. Kevlar is a popular choice for the jacket material.

It is strong and used to bundle and protect the loose tubes or fibers in the cable.

Kevlar protects the fibers when the tension is placed on the cable.

The color of this jacket typically depends on the type of fiber, single mode fibers typically wear a yellow

jacket and multi-mode fibers wear an orange jacket.
